<b>Key Features</b>
<i>Standards Support</i>
JRun 4 implements the complete J2EE platform specification, including Java Server Pages, Java Servlets, Enterprise JavaBeans, Java Message Services, and other Java and web services APIs.
- Certified J2EE 1.3-compatible: JRun 4 is certified J2EE 1.3-compatible, implementing the latest standards support for the complete Java 2 platform APIs.
- Advanced EJB 2.0 support: The JRun 4 EJB container has been rearchitected to provide superior support for the new EJB 2.0 features, including local interfaces, message-driven beans, EJB-QL, and Container Managed Persistence (CMP) 2.0.
- Web services integration: Building web services in JRun 4 is as simple as editing a deployment descriptor to expose your regular Java classes or Enterprise JavaBeans as web services. Consuming web services is equally easy: JRun 4 automatically generates Java proxies for web services based on their WSDL files. JRun 4 has integrated support for open web services protocols such as SOAP, WSDL, and UDDI.
<i>Presentation Services</i>
- Macromedia Flash MX remoting services: With built-in Macromedia Flash MX player connectivity, it's easy to provide your J2EE applications with a high-impact user interface. Macromedia Flash MX remoting allows user interfaces built in Macromedia Flash to connect to EJBs, Java classes, and MBeans simply, quickly, and securely.
- JRun Server Tags technology: JRun Server Tags (JST) allow you to write custom tags using JavaServer Pages, instead of the more complex custom tag handler. Custom tag development is faster and more approachable.
- Built-in web server: JRun 4 ships with a built-in, high-performance HTTP server. Additionally, JRun 4 provides connectors for support of other leading HTTP servers.
- High-performance web server connectors: High-performance and clustering-enabled web server connectors also allow you to use JRun 4 with all the major web servers, including Apache, Microsoft IIS, Netscape Enterprise Server, iPlanet, and Zeus.
<i>Performance and Scalability</i>
Superior performance and breakthrough Jini technology-based server-cluster management capabilities allow your applications to scale in a reliable and highly optimized runtime environment.
- Superior servlet and JSP performance: The elegant and small footprint architecture in JRun 4 is optimized for performance. Since its introduction in 1997, JRun is recognized as the fastest web container in the application server market.
- Advanced Jini technology-based server clustering: JRun 4 provides enterprise-class server clustering, allowing load balancing and automatic failover at all levels: web server, web connector, and component. JRun servers use Jini technology to dynamically locate their peers in the cluster, eliminating the risk inherent to a single point of failure.
- Performance tracing: Instrumentation allows you to identify and resolve performance bottlenecks in your code by tracing and timing each method invocation in your application. Instrumentation is supported for JSPs, servlets, and EJBs.
<i>Development and Deployment Services</i>
In addition to the core J2EE services, JRun 4 includes features to simplify and speed the development and deployment process. Using the power of the new JRun 4 development and deployment features, you can deliver your applications faster in a non-stop server environment.
- Auto deployment: Deploying an application is as simple as copying an EAR, JAR, WAR, or RAR file to the server directory. JRun 4 automatically senses the new file, deploys it, and makes it available in the target server: there's no need to restart the server.
- Hot Modification: During development, you can hot modify any application component (servlets, JavaServer Pages, Enterprise JavaBeans, Java classes, deployment descriptors). The changes take effect immediately, without restarting the server.
- XDoclet integration: XDoclet is tightly integrated into JRun 4. When modifications are made to the source file, JRun 4 will automatically generate the necessary auxiliary files, such as interfaces and deployment descriptors.
- EJB development and deployment tool: The Enterprise Deployment Wizard streamlines developing and deploying Enterprise JavaBeans. With new O/R mapping capabilities for CMP 1.1 and CMP 2.0, you can generate and deploy a fully-functional entity bean in minutes.
- IDE integration: JRun 4 integrates with industry-leading development tools, such as JBuilder, IntelliJ, Forte, and WebGain.
<i>Data Access Services</i>
- Bundled type IV JDBC drivers: JRun 4 comes with high performance JDBC drivers for the leading databases: Oracle, Microsoft SQL Server, Sybase, DB2, and Informix.
- Java API for XML parsing (JAXP): JRun 4 integrates a JAXP-compliant XML parser and an eXtensible Stylesheet Language Transformation (XSLT) engine.
<i>Application and Server Management</i>
- JRun Management Console: The redesigned, JMX-enabled JRun Management Console (JMC) provides an easy-to-use, web-based graphical user interface to manage your local and remote JRun servers. Using the JMC, you easily create servers, define clusters, manage applications, and implement JAAS-based security.
- Point-and-click server cluster administration: Installing and managing a cluster of JRun servers is straightforward. Using the JRun Management Console (JMC), you define and administer a cluster in a point-and-click environment. JRun 4 also simplifies the deployment of applications into a clustered environment. The JMC provides a one-step deployment option to all the servers in the cluster.
<i>Open and Extensible Architecture</i>
Built on an elegant JMX service-oriented architecture with a small footprint, the JRun 4 Server is easily customized, extended, or embedded to meet your unique business requirements.
- Service-oriented architecture: JRun 4 services—EJB container, web container, logging, and others—are implemented as MBeans plugged into the JMX-based JRun kernel. This plug-in architecture provides a highly customizable and easily extensible deployment platform.
- Java Message Service (JMS): JRun 4 includes a durable and transactable JMS 1.02b-compliant provider that supports both point-to-point and publish/subscribe synchronous and asynchronous messaging. JRun 4 can also be used in conjunction with an external JMS provider, such as SonicMQ.
- Small Disk Footprint: JRun 4 is a lean and efficient application server that does not carry the excess overhead that goes along with legacy technology. JRun 4 lets you control the components you install and activate to optimize memory resources at runtime.
